  Next, the operation of the elevator car according to the present embodiment having such a configuration will be described.

  In the elevator car as shown in FIG. 1, when the door 12a, 12b moves upward when reaching the boarding / exiting floor in the hoistway, the doorway of the car body 10 is opened.

  On the other hand, when the elevator car is moving up and down in the hoistway, the doors 12a and 12b are in the closed position as shown in FIG. 1 and block the doorway of the car body 10. Here, as shown in FIG. 4, an airtight state is formed between the upper three-way frame seal member 20 and the upper low-speed door seal member 30, and between the lower low-speed door seal member 31 and the upper high-speed door seal member 40. An airtight state is formed by the cushion rubber 14 between the bottom surface of the high-speed door 12b and the hole sill 13. Further, as shown in FIG. 6, airtightness is also provided between the side three-side frame seal member 22 and the side low-speed door seal member 32 and between the side three-side frame seal member 22 and the side high-speed door seal member 42. A state is formed.

  For this reason, when the doors 12a and 12b are in the closed position, the airtight state is maintained between the low speed door 12a, the high speed door 12b, and the three-way frame 11 by the seal members. As a result, the interior of the car body 10 is completely isolated from the outside air.

  According to the elevator car of the present embodiment, the three-way frame 11 is provided with the three-way frame seal members 20 and 22, and the doors 12a and 12b are provided with the door seal members 30, 31, 32, 40, and 42. When the doors 12a and 12b are in the closed position, the door seal members 30, 31, 32, 40, and 42 are in contact with the seal members of the other doors or the three-way frame seal members 20 and 22, and the interior of the car body 10 is airtight. It is supposed to be. For this reason, a smoke shielding function can be given to the entrance / exit of the elevator car by each of these seal members. Here, by simply attaching the seal members to the doors 12a and 12b and the three-way frame 11, the entrance and exit of the elevator car can have a smoke shielding function, so that the elevator car has a smoke shielding function. In addition, the elevator can be provided with a smoke shielding function without being restricted in the design and layout around the entrance / exit of the elevator.

  In addition, the elevator car by this Embodiment is not limited to said aspect, A various change can be added. For example, the number of doors 12 as shown in FIG. 1 is not limited to two, and a door with three doors 12 as shown in FIG. 12 may be used. Alternatively, the number of doors 12 may be four or more. When the number of doors 12 is three as shown in FIG. 12, the speed pulled upward from the closed position increases in the order of the high speed door 12b, the medium speed door 12c, and the low speed door 12a. . When the doors 12a, 12b and 12c are in the closed position, the upper edge portion of the low speed door 12a and the upper edge portion 11b of the three-way frame 11 are hermetically sealed by the upper low-speed door seal member 30 and the upper three-way frame seal member 20. The lower edge portion of the low speed door 12a and the upper edge portion of the medium speed door 12c are in an airtight state by the lower low speed door seal member 31 and the upper medium speed door seal member 50, The lower edge portion of the medium speed door 12 c and the upper edge portion of the high speed door 12 b are in an airtight state by the lower middle speed door seal member 51 and the upper high speed door seal member 40. Furthermore, the space between the side edge of each door and the side edge 11a of the three-way frame 11 is also airtight by the seal members. Thus, even when the number of doors 12 is three or more, the interior of the car body 10 can be kept airtight by attaching the door seal member to each door.

  Moreover, each door 12 is not limited to an upper opening door as shown in FIG. 1, and may be a lateral opening door.

Further, instead of directly attaching the door seal members 30, 31, 32, 40, 42 to the doors 12 as shown in FIGS. 4 to 6, the doors 12 and the door seals as shown in FIGS. The L-shaped bracket 15 may be interposed between the members 30, 31, 32, 40, and 42, respectively. In this case, as shown in FIG. 7 and the like, the L-shaped bracket 15 is attached to the edge of each door 12a, 12b, and each door seal member 30, 31, 32, 40, 42 is attached on the L-shaped bracket 15. Will be.
This method is used when the positions of the doors 12a, 12b and the three-way frame 11 do not match when attaching each seal member to an existing property. That is, by making holes in the doors 12a and 12b and attaching the L-shaped bracket 15 to the doors 12a and 12b, an airtight state can be formed between the seal members.

  Further, the three-sided frame sealing member attached to the three-sided frame 11 and the door sealing member attached to each door 12 are not limited to wedge-shaped ones as shown in FIGS. 4 to 6, but as shown in FIG. The L-shaped seal members 22a, 32a, and 42a may be used. In this case, an L-shaped portion of the three-way frame seal member or the door seal member is adapted to form an airtight state between the three-way frame seal member and the door seal member or between the door seal members. . As a result, it is possible to obtain the same operational effects as when wedge-shaped seal members such as those shown in FIGS. 4 to 6 are used.

  In still another modified example, as a three-sided frame sealing member attached to the three-sided frame 11 and a door sealing member attached to each door 12, concave or convex sealing members 22b and 32b as shown in FIG. , 42b may be used. In this case, as shown in FIG. 11, each door seal member has a concave shape or a convex shape that conforms to the concave shape, and each three-way frame seal member has a concave shape that conforms to the convex shape of the door seal member. It consists of things. Then, by fitting another convex door seal member into one concave door seal member or three-way frame seal member, an airtight state is established between the three-way frame seal member and the door seal member or between the door seal members. It is supposed to be formed. As a result, it is possible to obtain the same operational effects as when wedge-shaped seal members such as those shown in FIGS. 4 to 6 are used.

  Alternatively, as another modification, a convex three-way frame seal member may be used instead of the concave three-way frame seal member. In this case, the convex three-way frame seal member can be adapted to the concave door seal member. And, by fitting another convex door seal member or three-way frame seal member into one concave door seal member, an airtight state is established between the three-way frame seal member and the door seal member or between the door seal members. It is supposed to be formed. As a result, it is possible to obtain the same operational effects as when wedge-shaped seal members such as those shown in FIGS. 4 to 6 are used.

  As still another modification example, each three-sided frame seal member and each door seal member have a waveform as shown in FIG. 13 (for example, a three-sided frame seal member 60a and a door seal member 70a that are compatible with each other), FIG. 14 (for example, a three-way frame seal member 60b and a door seal member 70b that fit each other) or a U-shape (for example, a three-way frame that fits each other) as shown in FIG. Seal member 60c and door seal member 70c) can be used.
